I thought that creating a token as payment would accelerate the launch of the app, but instead, the token will limit the options for the users, so the way to go is to start with multiple payment methods like binance pay, coinbase to cover most of the coins.
Launching without funds is no fun, but it can be done.
I created a discord server for the project if anyone is interested in joining.
